Click the link to determine where ARM stores reports.
The default path is:
From 8MAN/ARM version 8 on reports will no longer be created in XPS format. For compatibility reasons the XPS viewer will stay included to view earlier created reports in XPS format.
By default ARM uses its own XPS viewer when opening files in an XPS format. The ARM user interface is locked when displaying XPS reports.
Please use the Microsoft XPS viewer if you require the simultaneous availability of both report and ARM user interface.
